'nn'rncnaiann COVER roaooLLarsIBLE oven casinos.

T aZZ wlz am it may concern Be it known that I, HENRY IQIEHLBERG, a citizen of the United States of America, and resident of Martins Ferry, county of Bel '5' mont, and State of Ohio, have invented certain new and useful lmprovements in 'Detachable Covers for Collapsible Oven Casings, of which the following is a specification. i

This invention relates broadly to sheet metal ovens of that type which embodies a collapsible casing, andmore specifically to a detachable cover for such ovens The primary object of the invention is .to

provide a simple and convenient form of detachable cover or top for collapsible oven casings of the type exemplified in my copending, or companion, application, Serial A further 'objectis to provide a detachable top-or cover by means of which the upper edges of the side and ends of aicollapsible oven casing are'rigidly braced in their normal extended positions.

A still further object is to provide simple means whereby the cover is detachably secured in place and by which, at the same time, is afforded means for attaching handles for lifting the oven.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which Figure 1 is an end elevation of the upper portion of a collapsible oven embodying my present invention; Y

Figure 2 is an under side elevation of the top or cover; and

Figure 3 is an enlarged fragmentary section on line 33, Fig. 1.

Referring to said drawings, 1 indicates the front wall, 1 the rearwardly directed front wall flange, 2 the rear wall, 2 the rear wall flange, and 3 the end panel of the collapsible sheet-metal oven casing disclosed in my said co-pending application, Serial No. 593,805.

Mounted upon the top of said casing is a top or cover comprising a rectangular sheet metal top-plate 4 which preferably has its ends and lateral'edges curled downward to form beads or rolls 4? and 4, respectively, adapted to more or less closely embrace or abut the upper edge portions of the sides and ends of the oven casing. Located at a suitably spaced distance below and substantially parallel to said top-plate 4 is a bottom-plate I i Application filed October 11,1922. Serial no. 593,806.

5., the same being rigidly attached to said top plate, as by means of suitably located bolts 6. Said bottom has its end portions bent to form upwardly and outwardly inclined flanges 7 provided withhorizontal terminals 7 and has its lateral edge portions similarly bent to form inclined flanges 8 with terminals 8 Said terminals 7 and 8 are preferably disposed in underlying seated relation to the top-plate 4 and are adapted to seat upon the upper edges of the casing walls, the latter when expanded in true rectangular form having their said upper edges closely engaged interiorly by the upper portions of the flanges 7 and 8 ofsaid bottoni-plate 5 and thus being firmly held or braced.

Attached to the under facelof the bottomplate 5 adjacent to each end of the latter, as

by means of rivets 9, is a plate 10 having integral therewith a pair of depending resilient fingers 11 located in suitably spaced relation. Each of said fingers has formed therein intermediate its ends an outwardly extending bow or loop 11*, and said loops are adapted to be projected outward through horizontallyalined holes 12 provided therefor in the adjacent end panel 3 of the oven casing, said fingers being suliiciently resilient to allow of said loops being sprung into and out of said'holes. To secure said loops against chance withdrawal from said holes, and thus to firmly secure the cover upon the casing, theoutwardly' projecting ends of each, pair of loops have received therein opposite laterally directed terminals 13 formed upon the ends of a loop-like resilient wire handle 14 which preferably has formed therein one or more spring coils 15 tending to hold the side members thereof thrust apart for preventing chance withdrawal of said terminals 13 from engagement with the loops 11 Not only does the handle 14 securely lock the finger-loops in place in the holes 12 of the casing whereby the top or cover is securely locked in place on said casing, but said loops serve as a mounting for said handle.

What is claimed is 1. The combination with a collapsible oven casing, of a cover for said casing comprising a sheet metal member adapted for mounting within the upper portion of said casing, said member having upwardly and outwardly inclined flanges for seating in interiorly bracing relation to the Walls of said casing, and resilient members carried by said cover adapted to be sprung into and out of interlocking relation to said casing.

2. The combination with a collapsible oven casing, of a cover for said casing comprising a sheet metal member adapted for mounting within the upper portion of said casing, said member having upwardly and outwardly inclined flanges for seating in interiorly bracing relation tothe walls of said casing, and resilient fingers depending from the opposite ends otsaid cover, said fingers having loops formed therein engageable with said casing for retaining said cover in place.

3. The combination with a collapsible oven casing, of a cover for said casing comprising a sheet metal member adapted for mounting within the upper portion of said casing, said member having upwardly and outwardly inclined flanges for seating in interiorly bracing relation to the walls of said. casing, and resilient fingers depending from the opposite ends of said cover, said fingers having loops formed therein adapted to be projected outward through the end walls of the casing, and means engageable with the projecting portions of said loops for securing the latter against retraction.

l The combination with a collapsible oven casing, of a cover for said casing comprising a sheet metal member adapted for mounting within the upper portion of said casing, said member having upwardly and outwardly inclined flanges for seating in in teriorly bracing relation to the walls of said casing, and resilient fingers depending from the opposite ends ofsaid cover, said fingers having loops formed therein adapted to be projected outward through the end walls of the casing, and handles engaged with the projecting loops.

5. In an oven, a collapsible casing having side and end walls in hinged relation, each of said end walls having a pair of horizontally alined holes in the upper edge portion thereof, acover mounted upon the top of said casing Walls in bracing relation to the latter, a pair of resilient fingers depending within said casing from each end of said cover, said fingers having loops formed therein adapted to be sprung through the said holes in the casing walls, and means detach-ably engaged with said loops for preventing withdrawal ot the latter from said holes.

6. In an oven, a collapsible casing having side and end walls in hinged relation, each of said end walls having a pair of horizontally alined holes in the upper edge portion thereof, a cover mounted upon the top of said casing walls in bracing relation to the latter, a pair of resilient fingers depending within said casing from each end of said cover, said fingers having loops formed therein adapted to be sprung through the said holes in the casing walls, and a looplike resilient Wire handle having terminals detachably engaged with said loops.

7. In an oven, a collapsible casing having side and end walls in hinged relation, each of said end walls having a pair of horizontally alined holes in the upper edge portion thereof, a cover mounted upon the top of said casing walls in bracing relation to the latter, a pair of resilient fingers depending within said casing from each end of said cover, said fingers having loops formed therein adapted to be sprung through the said holes in the casing walls, and a resilient wire handle having laterally directed terminals detac-hably engaging said loops.

In testimony whereof, I atfix my signature in presence of two subscribing witnesses'.
